Major James W. Bagley

Major James W. Bagley, U.S. Army, applied tools and techniques he helped develop as a civilian in the U.S. Geological Survey to help his country during World War I. As a USGS employee from 1905 to 1917, he mapped the topography of the Chugach Range in Alaska and developed a state-of-the-art panoramic camera, which vastly improved the scope of a surveyor’s photograph. During World War I, Major Bagley traveled to France as a member of the Corps of Engineers and developed the three-lens aerial camera, redefining what could be captured in a single flight. “[His] name is indelibly inscribed in the history of American photogrammetry,” stated his obituary in 1947.
